BACKGROUND

The present invention may relate to the implant attachment systems for attaching dental implant surgical guides to dental implants. More specifically, the present invention may relate to those implant attachment means that are used on dental implant surgical guides that may be subsequently incorporated into dental prostheses.

Dental implant surgical guides may be used for the placement of implant drills, implant reamers, dental implants, and other dental implements at a dental implant site in a mouth of a patient to help ensure that such placed dental implements achieve the proper and desired telemetry and location. Similarly, dental implant surgical guides can be used in practice on a model of a patient's mouth to test the placement and positioning of dental implements. Normally after the implants (e.g., post-type implants) have been placed in the mouth through the use of the dental implant surgical guide, the dental implant surgical guide could be removed from the mouth and generally be discarded. In some dental implant/prosthesis surgeries, a connecting bar may be further attached to the dental implants to substantially form a bar/implant configuration for the dental prosthesis attachment. After suitable testing and fitting, a prosthesis may then be attached to the dental implants and/or connecting bar/implant configuration to secure the dental prosthesis in the patient's mouth.

It has been found that the dental implant surgical guide could be used to replace the connecting bar to save on costs and labor in the implant process. The dental implant surgical guide can be further incorporated into the dental prosthesis by attaching the dental implant surgical guide within an open channel in the bottom of the dental prosthesis or by generally being enclosed within the dental prosthesis interior formed by two halves of a prosthesis. Rather than discarding the dental implant surgical guide, the dental implant surgical guide can be added to the dental prosthesis structure to generally increase the structural integrity and load-carrying capacity of the dental prosthesis.

One possible issue with the incorporation of the dental implant surgical guide into the dental prosthesis could be the attachment of the dental implant surgical guides to the placed dental implants. Generally to control the telemetry and position of the implants, dental implant surgical guides may have guide cylinders forming double open-ended guide channels through which the dental implants may pass to be located to the respective dental surgical site (or dental surgical site model). As such, dental implant surgical guides when located over the dental implants may have an open area, the guide channel, that is directly located over the placed implant thereby generally eliminating any material (e.g., metal) that may rest upon and be subsequently used to attach the dental implant surgical guide to the implant.

One possible solution to this issue could the present invention's attachment system of an abutment, an implant mounting and a cap. The abutment and implant mounting being combined with an otherwise unsecured implant outside of the dental implant surgical guide (e.g., outside of the patient's mouth) to form an implant combination wherein the implant, implant abutment, and most of the implant mount are able to pass though the guide channel. The implant mount at its otherwise unattached end could have a rim with a greater diameter/circumference than that of the guide channel so that the rim cannot pass through the guide channel. In this implant combination, the implant mount may be attached to one abutment end of the abutment, the abutment may be attached by its other abutment end to the implant to create a generally an overall columnar form. The assembled implant combination can then be inserted into the respective guide channel of the surgical guide. The implant mount can be engaged by a tool (e.g., wrench) so the entire combination can be moved within the guide channel to substantially allow threads of the implant to substantially engage the prepared implant shaft at the dental implant site. As the implant combination is generally secured to the dental surgical site (or model thereof), the rim may be drawn into contact with the top of guide cylinder. In this manner, the rim overall anchors the dental implant surgical guide to the implant in a manner that resists those outward forces that may pull the dental implant surgical guide way from the dental implant.

The cap could be subsequently attached to the top of the guide cylinder to sandwich the rim between the guide cylinder and cap to substantially resist those forces which may direct the dental implant surgical guide towards the implant. This cap attachment action may also move the dental implant surgical guide up tight against the rim in a manner to further bring the dental implant surgical guide into a more complete alignment with the placed implants.

DESCRIPTION OF CERTAIN EMBODIMENTS OF THE PRESENT INVENTION

In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part of this application. The drawings show, by way of illustration, specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention.

The present invention 10 could comprise an attachment system 20 and method or process 200 for operating same to attach a dental implant surgical guide to one or more dental implants located at a dental surgical site in a patient's mouth. The employment of the attachment system could allow the dental implant surgical guide to anchor a dental prosthesis to a patient's mouth.

As substantially shown in FIG. 1, a dental implant surgical guide 120 may be used to place one or more dental implants 100 at dental surgical site 12 in an implant shaft 18 at patient's mouth 16 or place dental implant analogues (not shown) in a model of the dental surgical site (not shown). A dental implant surgical guide 120 could comprise a guide body 122 that forms a set of spaced-apart guide cylinders 124. In one possible version, the guide cylinders 124 could be held apart by support bars 130 each having a trapezoidal cross-shape, the trapezoid's narrow flat being on the top of the support bar 130. The trapezoid cross-shape could be conductive to mount the prosthesis 140 (as substantially shown in FIGS. 3 and 11) to the dental implant surgical guide 120. Each guide cylinder 124 further forming double open-ended guide channel 128 that can continuously connect the dental implant surgical guide's top and bottom. The guide channel 128 can be confirmed to specifically receive various dental implements (e.g., implant drills, implant reamers, dental implants 100 and the like) to allow the securing of the dental implants 100 to a dental surgical site 12 of a patient's mouth 16 or to place dental implant analogues to dental surgical site models (not shown.) For use with the invention 10, the external side 134 of the guide cylinder 124 could feature a suitable locking interface 132 (e.g., be threaded) to allow attachment of a cap 72 (as substantially shown in FIGS. 4, 7, 10 and 11) to the guide cylinder top 126.

As substantially shown in FIG. 2, the dental implant 100 could be a standard post implant that may have a cylindrical implant body 102 with first tapered and threaded end 104 that that may be used to anchor the dental implant 100 to a bone at the dental surgical site 12. In some versions of the dental implant 100, the second implant end 106 have an open-ended implant recess 108 to accept the first abutment end 34 in a manner to attach the abutment 30 to the dental implant 100 by a variety of attachment devices (e.g., fastener, adhesive, and other securing means known in the art). (As substantially shown in FIG. 4). In one possible embodiment, the implant recess 108 may have a tapered side 110 (e.g., may be cone shaped) to substantially implement a Morse's taper or a taper interference fit as generally known in the art to attach a first abutment end 34 to the implant recess 108. Further, the tip of the implant recess 108 (e.g., tip of the cone) could generally define an implant aperture 112 suitably configured (e.g., threaded) to receive and attached to at least a portion of a first fastener 40. The first fastener 40 in this manner could be initially be used to secure the abutment 30 and dental implant 100 together (as substantially shown in FIG. 4). It should be noted that an analogue implant (not shown) with generally the same attributes as the described dental implant 100 could be substituted for the implant 100 to allow the invention 10 to apply a dental implant surgical guide to a dental surgical site model for testing, fitting and modification of the dental implant surgical guide, the prosthesis, the invention 10 and the like as needed (not shown).

As substantially shown in FIG. 3, one possible version of the prosthesis 140 could comprise of a prosthesis base 142 providing artificial gingiva or gum, the prosthesis base 142 further supporting one or more artificial teeth 144. The underside 146 of the prosthesis base 142 could further denote a channel 148 that could accept the dental implant surgical guide 120. In other embodiments, not shown, the dental prosthesis could be constructed into halves wherein the dental implant surgical guide in placed between the halves which are then closed together to generally encapsulate the dental implant surgical guide within the dental prosthesis.

As shown in FIG. 4, the system 20 could comprise an abutment 30, an implant mount 50 and a cap 72, wherein the abutment 30 may be used to secure the implant mount 50 to the implant 100 to form an implant combination 90, the implant combination 90 being moved through a guide channel 128 to place the implant 100 into the previously prepared implant shaft at the dental surgical site. A fastener-to-fastener connection provided by first and second fasteners 40, 68 may initially hold the implant combination 90 together. The implant mount 50 may have a rim 62 that cannot pass through the guide channel 128 and may be subsequently be drawn against the dental implant surgical guide 120 (as substantially shown in FIG. 11). The cap 72 substantially attaches to a respective guide cylinder 124 to securely seat the rim 62 against the dental implant surgical guide 120. This attachment action may substantially increase the contact of the rim 62 to the dental implant surgical guide 120 thereby bringing the dental implant surgical guide 120 up a desired final position relative to the one or more dental implants 100 placed at the dental surgical site 12.

As substantially shown in FIG. 5, the abutment 30 could have an abutment body 32 made of suitable material known in the art and the first fastener 40 that may movably penetrate through the abutment body 32. The abutment body 32 may have an overall exterior shape as would be substantially selected by those known in the art that generally promotes a suitable and healthy implant interface with the gum tissue and emergent sulcus. The abutment body 32 could further define a first and second abutment ends 34, 36 through which the first fastener 40 could pass. The first abutment end 34 could be tapered or conical-shaped to be generally reciprocal to the contours of the implant recess 108 to generally provide a taper interference fit (e.g., Morse's taper) between the dental implant 100 and abutment 30 when the first abutment end 34 is placed within the implant recess 108. The second abutment end 36 may have a contour that when received within the implant mount 50 could prevent the abutment 30 from rotating about the implant mount 50. In one possible embodiment, the second abutment end 36 may have a contour formed by a set of inclined flats 38 that may be seen to generally form an overall conical arrangement.

The first fastener 40 could be a threaded fastener and have a first fastener head 42 being large enough so that the first fastener head 42 does not pass through the abutment body 32. The first fastener 40 could be further capable of engaging the implant aperture 112 (e.g., threaded) of an implant recess 108 to initially secure the abutment 40 to the dental implant 100. In one possible embodiment, the first threaded fastener 40 could be generally held captive by the abutment body 32 for safety and efficiency reasons. The first fastener 40 could further be a bolt wherein the bolt's head is shaped with flats for removable engagement by a suitable wrench (not shown). The first fastener head 42 could further feature an open-ended fastener recess 44 to which a second fastener 68 could be attached and generally allowing for the attachment of the implant mount 50 to the abutment 30 (as substantially shown in FIG. 4).

As substantially shown in FIG. 6, the implant mount 50 could comprise a cylindrically-shaped mount body 52 and a second fastener 68 that movable penetrates through the mount body 52. The mount body 52 could be made of suitable materials as known and selected by the art and generally terminating in the first mount end 54 and a second mount end 58. The first mount end 54 could feature an open-ended abutment cavity 56 that has a contour 66 (e.g., inclined flats) that generally matches the form of the second abutment end 36. In this manner, when the second abutment end 36 may be placed within the abutment cavity 56, the second abutment end 36 may engage the abutment cavity 56 in a way that substantially prevents rotation of second abutment end 36 within the abutment cavity 56 (as substantially shown in FIG. 4).

The second mount end 58 could have a mount depression 60 that could accommodate the second fastener head 70 so that second fastener head 70 may not protrude above the second mount end 58 when the second fastener 68 is connected to the first fastener 40. The mount depression 60 could be further suitably fashioned to removably accept a tool 14 that can rotate the assembled or completed implant configuration 90 relative to the dental surgical guide 120, as well as implant shaft 18 (as substantially shown in FIG. 9).

The second mount end 58 may have an outwardly projecting protrusion such as a lip or rim 62 whose overall size is too large to allow the rim 62 fit into or through the guide channel 128 but the remainder of the mount body 52 is sized to pass though the guide channel 128. The rim 62 could have a rim circumference 64 that is generally greater than the circumference of the guide channel 128 but not greater than the circumference of the guide cylinder top 126 to provide sufficient implant mount retention capability.

The second fastener 68 could be also threaded (e.g., be a threaded bolt) and have a second fastener head 70 being large enough so that the second fastener head 70 does not pass through the mount body 52. The second fastener 68 could be further capable of engaging the fastener recess 44 so as to connect (e.g., removably) the second fastener 68 to the first fastener 40. This fastener-to-fastener connection could allow the implant mount 50 to be removably attached to the abutment 30 and further provide for the unification of the implant mount 50, abutment 30 and dental implant 100 when assembled into the implant combination 90 outside the patient's mouth. In this manner, the assembled implant combination 90 can then be inserted into the guide channel 128 and rotated as an single unit to drive and anchor the dental implant 100 into a previously prepared dental surgical site 12 (e.g., implant shaft 18) and to generally bring the rim 62 into contact with the guide cylinder 124 (as substantially shown in FIG. 4).

As substantially shown in FIG. 7, the cap 72 could be a hollow cap cylinder 74 with one enclosed cap end 76 and one open cap end 78. The cap cylinder wall's interior side 80 as proximate to the open cap end 78 could be feature a suitable cap locking interface 82 such as cap threads 86 to generally allow the cap 72 to be removably attached to the guide cylinder 124. As so attached, the cap 72 could generally cover both the second mount end 58 (e.g., rim 62) and the guide cylinder's top 126. The attachment of the cap 72 to the dental implant 100 in such circumstances could also be used to fully bring up the dental implant surgical guide 120 into significant contact with the rim 62. This rim contact could insure that dental implant surgical guide 120 is brought into final and desired telemetry and positioning as relates to the one or more placed dental implants 100. Further, the cap 72 and dental implant surgical guide 120 when so combined may further substantially secure the implant combination 90 to the dental implant surgical guide 120 to generally provide a resistance to those forces pushing the dental implant surgical guide 120 (e.g., as attached to the dental prosthesis 140) toward the one or more located dental implants 100 placed at the dental surgical site 12 (as substantially shown in FIG. 4).

The cap 72 could further have a suitable cap fixture 84 (e.g. such as a hexagon-shaped tool aperture in the center of the enclosed end 76) that can accept a suitable tool (e.g., a wrench—not shown) that can be used to attach (e.g., rotate) the cap 72 onto the dental implant surgical guide 120. In some embodiments, the cap 72 may be removably attached to the dental implant surgical guide 120.

As substantially shown in FIG. 8, the implant mount 50, the abutment 30 and the implant 100 could be assembled together (e.g., away from the dental implant surgical guide 120, outside of the patient's mouth 12 or both) to form the implant combination 90. The first fastener 40 (generally penetrating the abutment 30) can attach to the implant aperture 112 to bring the abutment 30 and the implant 100 together allowing the first abutment end 34 to mate within the implant recess 108. This tapered mating could bring into a force a taper interference connection (e.g., Morse's taper) between the abutment 30 and the implant 100. The second abutment end 36 can be brought into contact within the abutment cavity 56 of the implant mount 50 so that the flats 38 of the second abutment end 36 and the contour 66 (e.g., inclined flats) of abutment cavity 56 are brought into contact and alignment with one another. The second fastener 68 may further facilitate this contact by substantially engaging the fastener recess 44 in a fastener-to-fastener connection. The second abutment end's inability to rotate within the abutment cavity 56 (e.g., use of reciprocal flats 38) allows a rotation of the implant mount 50 to transmit a torsional force to the combined abutment 30 and implant 100 without placing the second fastener 68 under undue stress (e.g., a shearing force) when driving in the implant 100 into the implant shaft 18. This connection allows the implant mount 50 to be subsequently removed from the placed implant combination 90 (e.g., after being generally anchored at the dental implant site 12) if the dental implant surgical guide 120 needs to be removed from the placed implant combination 90. This same rotation or torsion force as transmitted to the implant combination 90 and hence imparted to the abutment-implant connection should increase the adhesion capability of the taper interference fit.

As substantially shown in FIG. 8, the assembled implant combination 90 can be placed through the guide channel 128 to bring the dental implant 100 into contact with prepared implant shaft 18 as substantially denoted by bone, namely mandible, maxilla. A tool 14 (e.g., a wrench) substantially connects with the mount depression 60 to rotate the assembled implant combination 90 (e.g., relative to both the dental implant surgical guide 120 and the dental surgical site 12) until the dental implant 100 is properly attached to and situated within the dental surgical site 12. If an implant analogue (not shown) is used instead of the implant 100 to form an analogue implant combination (not shown), then tool 14 can be similarly be used to rotate the analogue implant combination to properly attach and situate said implant analogue relative to the model dental surgical site (not shown).

As substantially shown in FIG. 9, once the implant combination 90 and alike is suitably placed and secured (e.g., dental surgical site 12, model dental implant site), the cap 72 can be placed over the top 126 of the guide cylinder 124 through which the implant combination 90 (or analogue implant combination—not shown) is generally located. A suitable tool (e.g., wrench—not shown) can engage the cap fixture 84 to substantially move (e.g., rotate) the cap 72 relative to the guide cylinder 124 so that the cap locking interface 82 can engage the locking interface 132 of the guide cylinder 124 to substantially draw the guide cylinder 124 into the cap 72 (e.g., screwing the cap 72 on to the threaded guide cylinder 124.) In this manner, the enclosed cap end 76 can impinge upon the second mount end 58 to securely press upon the rim 62, substantially sandwiching the rim 62 in between the enclosed cap end 76 and the guide cylinder top 126. In this manner, the sandwiched rim 62 could fully anchor the dental implant surgical guide 120 to the dental surgical site 12. This attachment combination may further resist those forces, which may attempt to move the dental implant surgical guide 120 (e.g., the attached prosthesis) away from or to the one or more implants 100 to which the dental implant surgical guide 120 is secured.

The cap attachment could be one of the last steps under taken prior to the attachment of the prosthesis 140 to the dental implant surgical guide 120. In that manner, the attachment of caps 72 to the respective implant combinations 90 as place through the guide channels 128 of the dental implant surgical guide 120 could be accomplished using an alternating sequence, such as tightening first the caps 72 located proximate to the back of the mouth 16 and moving towards those caps 72 located proximate to the front of the mouth 16.

As substantially shown in FIG. 11, once the caps 72 have been appropriately secured to the dental implant surgical guide 120, the prosthesis 140 can be secured to the dental implant surgical guide 120. In the embodiment using an enveloping dental prosthesis (not shown), the bottom half of the prosthesis could be attached to the dental implant surgical guide prior to the attachment by the system. The bottom half and dental implant surgical guide as combined could then be attached to the mouth using the system. Once so secured, the caps could be attached to the dental implant surgical guide and the top half of the prosthesis placed over the bottom half to substantially encapsulate the dental implant surgical guide within the enveloping dental prosthesis.

As substantially shown in FIG. 12, the process or method 200 of using the invention 10 could start with step 202, preparing the dental surgical site. In preparing the dental surgical site, the dental implant surgical guide could be suitably be brought proximate (e.g., attached by suitable method and means) to the dental surgical site. Dental implants (e.g., implant drills, implant reamers, and the like) could pass into respective guide channels to be directed to create the implant shafts that could receive dental implants. When this step is substantially completed, the process 200 could proceed to step 204, the assembling of the implant combination. For the encapsulating prosthesis, the bottom half of the prosthesis could be attached to the dental implant surgical guide.

In step 204, the assembling of the implant combination, the abutment can be first attached to the implant with the first abutment end being placed into the implant recess for a generally conical fit that can result in a taper interference fit or Morse's taper connection. The first fastener movably located through the abutment can then attach to the implant aperture at the tip of the conical fit to further hold the abutment and implant together. The implant mount can be connected to the abutment by placing the second abutment end within the abutment cavity of the implant mount so that the flats of the abutment cavity may be aligned with the flats of the second abutment end. The second fastener, movably located in the implant mount, may removably attach to the head of the first fastener to generally hold the implant mount in place upon the second abutment end and to generally complete the assembly of the implant combination. Depending on the number of dental implants that are needed, this step can be repeated several times to complete several implant combinations. Once this step is substantially completed, process 200 could proceed to step 206, placing the dental implant.

In step 206, placing the dental implant, the implant combination could be guided through the guide cylinder top to pass at least a portion of the implant combination through a respective guide channel (and through the bottom prosthesis half). The tip of the implant could initially engage the respective previously prepared implant shaft at the dental surgical site. If an implant analogue is used instead of the dental implant in the assembly of the implant combination, the implant analogue could be directed to an implant analogue shaft at a dental surgical site model. A suitable tool could be attached the second mount end (e.g., a wrench attached to the mount fixture) and the operator such as a dental health care professional can rotate the entire implant combination within the guide cylinder to drive the implant (e.g., or implant analogue) into the implant shaft. Once the implant and hence implant combination is firmly and properly seated within the dental surgical site, the step can be repeated for each additional implant combination that needs to be attached to the dental surgical site (or the dental surgical site model). Generally during this action, the second mount end is substantially brought into closer proximity to the respective cylinder, namely the rim may make contact with guided cylinder top. As this step is substantially completed, the process 200 may proceed to step 208, making adjustments.

In step 208, making adjustments, this is an optional step wherein the implant mount may need to be released from a placed implant combination to allow for removal of the dental implant surgical guide (prosthesis bottom half) from the implant combination. In such a situation, the second fastener may be disconnected from the first fastener so that the implant mount may be removed from the abutment. Depending on the number of implant combinations being located at that time, their respective implant mounts may need to be removed to allow for the full detachment of the dental implant surgical guide from the dental surgical site (or the dental surgical site model).

Once the adjustment, correction, fitting, or the alike has been be made, the dental implant surgical guide could be replaced over the abutments and the implant mounts could be suitably reattached to their respective abutments. This step can be repeated as needed to make the many adjustments, corrections, fittings, or the alike as needed. Once this step is substantially completed, the process 200 could proceed to step 210, fitting the cap.

In step 210, fitting the cap, the cap could be applied to a respective guide cylinder. A suitable tool (e.g., wrench) could be applied to mount fixture on the cap's enclosed end. The cap open end could be directed to and engage the top of the respective cylinder (e.g., the cylinder substantially holding the placed implant combination) so that the cap locking interface (e.g., cap threads) can engage the guide cylinder's locking interface (guide threads). Once the cap has fully engaged the guide cylinder, the tool can be removed. For multiple cap/guide cylinder applications, the caps can be applied and tighten in sequenced order that substantially eliminates possible warped placement of the dental implant surgical guide to the implants and to generally ensured dental implant surgical guide achieves the desired telemetry and position relative to the implants (and patient's mouth).

It should be noted that if needed the caps could be removed from guide cylinders, the implant mounts from the abutments, to release the dental implant surgical guide from the implants (or implant analogues).

As this step is substantially completed, the process 200 could proceed to step 212 attaching the prosthesis. In one version of the prosthesis, the dental implant surgical guide could be attached to the base channel. For the encapsulating or enveloping prosthesis, the prosthesis top half could be attached to the combined dental implant surgical guide and prosthesis bottom half to secure and envelope the dental implant surgical guide within the prosthesis. At the substantial completion of this step, the process 200 could proceed back to step 202 as needed.

CONCLUSION

Although the description above contains many specifications, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents rather than by the examples given.

As substantially shown in the drawings and generally described in the description, the invention could be a system for attachment of a dental implant surgical guide to one or more implants that allow the dental implant surgical guide to support a prosthesis and secure the prosthesis to the patient's mouth. The system could provide an implant combination that can be used to rotate an implant into place in a dental surgical site. In doing so the implant combination can bring a rim from the implant combination into contact with the guide cylinder top of the dental implant surgical guide. A cap attaching to the rim and dental implant surgical guide can then lock the dental implant surgical guide in place with one or more implant combinations to appropriately attach the dental implant surgical guide to the patient's mouth, allowing the dental implant surgical guide to anchor and support a dental prosthesis.
